Introduction: Improper lifestyle is one of the factors affecting the incidence of chronic diseases. According to the World Health Organization statistics, smoking causes four million deaths annually. Studies show that in 1993, 28.6% men and 3.6% of women older than 15 years in the country were smokers. The most practical stage behavior change model is Transtheoretical model. Therefore, this study used this model.
Methods: This cross-sectional study was done on 200 smokers or ex- smokers of Khorramabad who had high school diploma or higher educational levels. Cluster sampling was conducted in two stages. Data was collected by a questionnaire whose validity and reliability had been approved. Data was analyzed by using SPSS statistical software 11.5 and descriptive statistics. P level <0.05 was considered as significant.
Results: Mean age was 42.5±7.85 years. Regarding stages of change, 39.5% were in pre-contemplation stage, 25.5% in contemplation stage, 12% in preparation stage, 5.5% in action stage and 17.5% were in maintenance stage. Variables that had a significant relationship with stages of change included years of smoking (p=0.001), complications of smoking (0.000), and age (p=0.04). There was no significant relationship between marital status, education, family and income, and stages of change.
Conclusion: In this study, majority of the population under study were in the early stages. It is therefore necessary to provide educational programs and develop strategies for the same. Due to the significant relationship between age and years of smoking and exposure to advanced stages of change, people should be made aware of the problems of smoking earlier so that they can decide as soon as possible about smoking cessation.
